Numerical Control Machining
15.1 Introduction
Manufacturing a part is the culmination of product design. We discussed the manufacturing and CAM processes in Chapter 1, “Getting Started.” A variety of manufacturing processes exists. A manufacturing engineer (process planner) selects a suitable manufacturing process for the part material and design tolerances. A process planner typically has a strong background in and knowledge of manufacturing processes. With this knowledge, the planner may request design changes from the design engineers to simplify part manufacturing and, as a result, reduce manufacturing cost. For example, machining a flat blind hole is harder and more expensive than machining a conical blind hole. The former ...
